We've made no secret of our interest in Metaplace as a virtual world with enormous potential for various public good applications, combining the accessibility of a web-based environment with powerful creation tools. Now they set the bar even higher by adding voice chat functionality!
Here's a little video of a test voice chat between myself, my colleague Joyce and ZimZam, one of the developers at Metaplace.
It's dead simple to operate voice chat. Just go to a world that supports it (in this case the "Dating Game"), click on the ctrl key, and start talking! You obviously need to have access to a microphone and speakers / headphones on your computer. But for most users it will work out-of-the-box.
Installing it on your world is just a matter of buying the free module and enabling it in your place. Then invite some friends over and let the gabbing begin.
